Radium boot polish.
This boot polish never had any radium in it, of that you can be 99% sure. The word "radium" was widely used in the early to mid 1900s as a sort of designation of quality and brightness, based on its use in luminous paints. Just as today we have "titanium" padlocks that contain no titanium, or "titanium" clocks made of gray plastic that looks at best vaguely metallic, in the past there were countless "radium" products that contained no actual radium.Source:eBay seller northernkollectorContributor:Theodore GrayAcquired:14 June, 2008Text Updated:14 June, 2008Price: $25Size: 3"Purity: 0%
